No, actuallly. The 'squishy' is the ice crystals from being frozen several times, tearing the cells of the body apart.
It happens with meat and veggies too. Try putting a green onion in the freezer, and see how mushy it turns, it's because it doesn't have the 'strength' to withstand the ice crystals when it's freezing, and as they grow, they rip the onion to pieces (microscopically).
